WASHINGTON — They seem right out of a Hollywood fantasy, and they are: Cars that drive themselves have appeared in movies like “I, Robot” and the television show “Knight Rider.”
Now, two years after Google invented one, automated cars could be on their way to a freeway near you. In the U.S., California and other states are rewriting the rules of the road to make way for driverless cars. Just one problem: What happens to the millions of people who make a living driving cars and trucks — jobs that always have seemed sheltered from the onslaught of technology?
“All those jobs are going to disappear in the next 25 years,” predicts Moshe Vardi, a computer scientist at Rice University in Houston. “Driving by people will look quaint; it will look like a horse and buggy.”
If automation can unseat bus drivers, urban deliverymen, long-haul truckers, even cabbies, is any job safe?
Vardi poses an equally scary question: “Are we prepared for an economy in which 50 percent of people aren’t working?”
An Associated Press analysis of employment data from 20 countries found that millions of mid-skill, mid-pay jobs already have disappeared over the past five years, and they are the jobs that form the backbone of the middle class in developed countries.
That experience has left a growing number of technologists and economists wondering what lies ahead. Will middle-class jobs return when the global economy recovers, or are they lost forever because of the advance of technology? The answer may not be known for years, perhaps decades: Experts argue among themselves whether the job market will recover, muddle along or get much worse.
To understand their arguments, it helps to understand the past.
Every time a transformative invention took hold over the past two centuries — whether the steamboat in the 1820s or the locomotive in the 1850s or the telegraph or the telephone — businesses would disappear and workers would lose jobs. But new businesses would emerge that employed even more.
At the beginning of the personal computer age in the early 1980s, economists thought computers would do what machines had done for two centuries — eliminate jobs that required brawn, not brains. Low-level workers would be forced to seek training to qualify for jobs that required more skills. They’d become more productive and earn more money. The process would be the same as when mechanization replaced manual labor on the farm a century ago; workers moved to the city and got factory jobs that required higher skills but paid more.
But it hasn’t quite worked out that way. It turns out that computers most easily target jobs that involve routines, whatever skill level they require. And the most vulnerable of these jobs, economists have found, tend to employ mid-skill workers, even those held by people with college degrees — the very jobs that support a middle-class, consumer economy.
So the rise of computer technology poses a threat that previous generations of machines didn’t: The old machines replaced human brawn but created jobs that required human brains. The new machines threaten both.
“Technological change is more encompassing and moving faster and making it harder and harder to find things that people have a comparative advantage in” versus machines, said David Autor, an economist at the Massachusetts Institute of Technology who has studied the loss of mid-pay jobs to technology.
Here are the three scenarios that economists and technologists offer about jobs in the future:
THE ECONOMY RETURNS TO HEALTH AFTER A WRENCHING TRANSITION: It has always happened before. Europe and the United States endured repeated economic and social upheaval during the 19th and early 20th centuries as their agricultural economies transformed into industrial ones. Columbia’s Stiglitz argues that such pressures led to the collapse of the world economy in 1929 — the cataclysm we call the Great Depression.
Worldwide, the mechanization of farming caused agricultural production to soar in the 1920s — and crop and livestock prices to plunge by 50 percent between 1929 and 1932. In the U.S., farmers, who accounted for a fifth of the workforce, lost purchasing power and struggled to pay their mortgages and other loans. As their debts went bad, banks began to collapse, squeezing credit and spreading panic. The economy went into free-fall.
Only World War II — and the massive rearmament program it required — restored the U.S. economy to full health. The experience was traumatizing. And today only 2 percent of Americans work on farms.
“Economies don’t make these transitions well,” Stiglitz said. People in the dying parts of the economy can’t afford to invest in the education or retraining they need to find different work. “So you get workers trapped in the wrong sectors or unemployed,” he said.
“There is a period of time that is extremely disruptive,” said Thomas Schneider, CEO of the consultancy Restructuring Associates. “If you’re 55 years old now and lose your job, the odds of you ever getting hired into what you were doing before is as close to zero as you can imagine. If you are a 12-year-old, you have a very bright future. It’s just not doing what your father was doing or your mother was doing.”
THE ECONOMY CONTINUES TO PRODUCE JOBS, JUST NOT ENOUGH GOOD ONES: Some economists worry that the sluggish, lopsided labor market of the past five years is what we’ll be stuck with in the future.
Smarter machines and niftier software will continue to replace more and more mid-pay jobs, making businesses more productive and swelling profits.
The most highly skilled workers — those who can use machines to be more productive but can’t be replaced by them — will continue to prosper. Many low-pay jobs are likely to remain sheltered from the technological offensive: Robots are too clumsy to tidy up hotel rooms or clear dirty dishes at busy restaurants.
Under this scenario, technology could continue to push economic growth — but only a few would enjoy the benefits. More people would be competing for mid-pay jobs, so pay would shrivel. Many mid-skill workers would be left unemployed or shunted into low-skill, low-pay jobs. The income gap between the rich and ordinary citizens, already at record levels in many developed countries, would continue to widen.
TECHNOLOGY LEADS TO MASS UNEMPLOYMENT: In a speech last year, former U.S. Treasury Secretary Lawrence Summers declared that the biggest economic issue of the future would not be the federal debt or competition from China but “the dramatic transformations that technology is bringing about.”
Summers imagined a machine called the “Doer” that could make anything or provide any service. Productivity would soar. Wonderful goods and services would emerge. Enormous wealth would go “to those who design better Doers, to those who could think of better things for Doers to do.” But everyone else would be worthless in the labor market.
Summers put forward that the world is moving in that direction and has completed only 15 percent of the journey, but already we are “observing its consequences.”
Consequences, indeed. ATMs dislodged bank tellers. Microsoft Outlook manages what secretaries used to do. Expedia is replacing travel agents. E-ZPass is doing away with toll-booth operators. And robots continue to supplant factory workers.
But surely some jobs are safe. Truck drivers, perhaps? A machine can’t negotiate a left-hand turn against oncoming traffic without a human behind the wheel, can it? Or so economists Frank Levy of MIT and Richard Murnane of Harvard University reasoned in their book “The Division of Labor,” way back in 2004.
Six years later, Google developed a car that could drive itself, crossing the Golden Gate Bridge, circling Lake Tahoe and cruising down Hollywood Boulevard. The gee-whiz driverless car could soon claim victims in the job market.
“Twice a week, a truck comes near my house, and two guys get out and pick up the garbage,” said Vardi, the Rice computer scientist. “This will disappear. There will still be a truck coming, but it will be driven autonomously, and the garbage will be picked up autonomously, and those jobs will be gone.”
In the United States alone, 92,000 people are employed as sanitation workers, according to the Bureau of Labor Statistics. Add all other driving occupations, from long-haul truckers to taxi cab drivers, and the total exceeds 4 million. All those jobs may be in danger.
And that’s the future: Other occupations already are disappearing. Add up the jobs that technology can take across dozens of occupations and the result, Vardi and others warn, is unemployment on a scale we haven’t begun to imagine.
In his book “The Lights in the Tunnel,” Martin Ford foresees a computer-dominated economy with 75 percent unemployment before the end of this century. The vast majority of workers, he predicts, won’t be able to develop the skills necessary to outrun job-killing computers and robots.
“People talk about the future, creating new industries and new businesses,” Ford said. “But there’s every indication that these are not going to be in labor-intensive industries. … Right from the get-go, they’re going to be digital.”
Consider the great business successes of the Internet age: Apple employs 80,000 people worldwide, Google 54,000, Facebook 4,300. Combined, those three superstar companies employ less than a quarter of the 600,000 people General Motors had in the 1970s. T oday, GM employs just 202,000 people, while making more cars than ever.
As far back as 1958, American union leader Walter Reuther recalled going through a Ford Motor plant that was already automated. A company manager goaded him: “Aren’t you worried about how you’re going to collect union dues from all these machines?”
“The thought that occurred to me,” Reuther replied, “was how are you going to sell cars to these machines?”
